    Are you sure it's just not clutch chatter?

    Is it a single knock or a series of knocks? Does it become more frequent as speed increases?

    The first thing that came to my mind was perhaps the intake knocking around in the fender or something ( if its a CAI )... or a motor or trans mount. How about if your in neutral and just rev the engine sitting still do you hear the knocking noise? How many miles are on the vehicle?

    Could be the pitch stop mount in the rear of the engine. As the motor torques, you may be hearing it knock against the mount. Or it could be an engine mount, trans mount, or rear diff mount (if you hear it in the rear of the car)
